Channel decoding method and device

TL;DR: In this paper, a processing method, device and system for an overlapped multiplexing system is presented, which comprises: obtaining an input symbol sequence, the number of times of overlapped MIMO, and a multiplexed waveform; obtaining an initial value of a shift register according to the input symbols sequence and the number OFMIMO times, and performing convolutional encoding according to input symbols and shift register values to obtain an encoded signal, which resolves the technical problem in the prior art of being unable to perform continuous processing at a receive end.

TL;DR: In this paper, a decoder (40) is provided which is configured to operate upon an input encoded sequence using a wrap around Viterbi procedure, and a decoding method which employs the decoder.

TL;DR: In this paper, the authors proposed a channel decoding method which comprises the following steps: calculating output values of all states of a tail-biting convolutional encoder and correlation values of data to be decoded as branch measurement values; accumulating measurement values of corresponding states and the branch measurement value according to a state transition diagram, selecting a larger accumulated value as a new measurement value of a next state and storing selection results until the data-to-end up.

TL;DR: In this article, a trace decoding method in a Viterbi decoder is described, starting up trace after the information and selection decisions are stored into the decoding depth, storing the information into the decoder corresponding to each time scale for beginning the trace and reading the stored more than one pieces of information to trace more nodes, when the trace reaches to the depth, it decodes input codes.

TL;DR: In this paper, a Viterbi decoder with a branch measurement computing unit, an adding, comparing and selecting unit, a path measured storage, a survive path storage and a trace unit is used.
